Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

30 hurt as airliner hits turbulence

Posted by feww on August 3, 2009

Severe turbulence shakes Continental airliner near Dominican Republic

A Continental airliner flying from Rio de Janeiro, Brazil, to Houston, Texas,  Monday experienced severe turbulence at 36,000 feet, injuring more than 30 passengers—at least 4 of them seriously—and forcing the plane to divert to Miami International Airport.

“There were 168 passengers on Flight 128, which was originally headed from Rio de Janeiro, Brazil, to Houston, Texas, according to Lt. Elkin Sierra of the Miami-Dade Fire Department.” CNN reported.

Some of the injured were taken to hospitals in Miami, while others  with less serious injuries were treated on the spot after the plane landed at Miami International Airport at about 6 am ET.

“The Boeing 767 hit turbulence about 50 miles north of the Dominican Republic at about 38,000 feet, according to an official with the Federal Aviation Administration.”

“The airline will decide whether or not to leave the uninjured passengers on the aircraft and continue the flight or disembark the entire aircraft,” Sierra said.
